Lift the home bar up as high as it will go, but not so high that the wires disconnect.

Try to bend the small tab under the silver rim as little as possible it the following steps. The more you bend, the more likely it will snap.

Twist the home bar counter clockwise while carefully lifting it further. The left edge has to lift over the black plastic frame to allow it to rotate.

The home bar should now lift out of the PSP 300xc.
